Where is the air pressure valve


Air pressure valves are valves which maintain pressure of air in the system in which the valve is installed. Common valve is used to provide pressurised air as an input to the "Pressure gauge" to measure the pressure.

    I have a service engine soon light on and have hooked up an OBD11 reader to it and got code P0410 pertaining to a secondary air injection problem. hoses are fine, pump is new.


    P0410 Oldsmobile - Secondary Air Injection System Malfunction

    Possible causes: - Faulty Vacuum hoses damaged
    - Faulty Air Pump inoperative
    - Air bypass solenoid harness is open or shorted
    - Air bypass solenoid circuit poor electrical connection
    - Air bypass solenoid leaking/blocked or stuck open/closed
    - Air diverter valve leaking/blocked or stuck open/closed

    Tech notes: Visually inspect AIR pump and AIR bypass valve harness and connector, if connector are OK, then replaced AIR bypass valve.

    When is the code detected? The secondary air injection system does not detect the presence of air in the exhaust when introduced by the secondary air injection system.

    Possible symptoms: - Engine Light ON (or Service Engine Soon Warning Light)
    - Engine hesitation

    P0410 Oldsmobile Description An air pump is used on the vehicle to lower tail pipe emissions on start-up. The Powertrain Control Module (PCM) grounds the Air pump relay control circuit which energizes the Air pump. The PCM also grounds the Air combination valve vacuum control solenoid circuit, which energizes the Air vacuum control solenoid. Vacuum is then applied to both Air combination valve diaphragms which opens the shut off valves. The PCM enables both circuits simultaneously when Air system operations id desired. When the AIR system is active, then Air pump forces fresh air into the exhaust stream in order to accelerate catalyst operation. The AIR combination valves replace the conventional check valves. When the AIR system is inactive the shut off valves prevent air flow in either direction.

    Bostitch 2 hp , 4.5 gal. compressor leaks air out of air cleaner


    Air leaking air out of intake when the compressor is not running and pressure in tank indicates bad check valve. Follow the discharge tube to where it connects at the brass valve mounted to tank. This valve is a non-return valve and can be replaced with generic valve. When air blows or pulsates out of intake as the compressor is running is indication that pump has bad valves or blown gasket/ gaskets. Good luck

    Check engine code P0418 comes on


    P0418 Secondary Air Injection System Relay 'A" Circuit Malfunction.
    The DTC P0418 is detected the the AIR vacuum control solenoid circuit not operating as desired by the PCM.

    An air pump is used on the vehicle to lower tail pipe emissions on start-up. The Powertrain Control Module PCM grounds the Air pump relay control circuit which energizes the Air pump. The PCM also grounds the Air combination valve vacuum control solenoid circuit, which energizes the Air vacuum control solenoid.

    Symptoms:
    - Engine Light ON (or Service Engine Soon Warning Light)
    - Engine hesitation

    Possible Causes:
    - Air Pump inoperative.
    - Air bypass solenoid circuit open or shorted.
    - Faulty AIR byspass solenoid circuit

    Possible Solution:
    - Visually inspect AIR pump harness and connector. Repair if necessary.
    - Visually inspect AIR bypass valve harness and connector. Repair if necessary.
    - Replaced AIR bypass valve
    - Replaced Air pump

    Poor supply air pressure


    3 stage? It sounds like the first stage has a leaking valve, possibly second stage also - this would explain both the high temperature in stage 1 and the poor pressure from the final stage. Take a look at page 6 of the following link. This is the typical intake and outlet valve diagram for each stage. Valves #2 are intake valves, and valves #6 and 7 are discharge valves. They all perform like check valves, each valve allowing air flow in only one direction. It sounds like your valves are leaking between 1st and 2nd stages. Possibly debris in the valves, or valves damaged. Try taking air intake filter off and check for damage to air filter and debris at intake. Also try removing valve plates and check for debris/damaged valves on first and second stages.
